SOLUTION: What is the point of intersection/whether the point is a solution for: 2x + y = 3 -x + 3y = -12 Thanks. x

Question 804941: What is the point of intersection/whether the point is a solution for:
2x + y = 3
-x + 3y = -12
Thanks. x
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
2x + y = 3
-x + 3y = -12
------
Modify for elimination::
2x +y = 3
-2x + 6y = -24
------------------
Add and solve for "y":
7y = -21
y = -3
------
Solve for "x":
2x + y = 3
2x -3 = 3
2x = 6
x = 3
----
Solution: (3,-3)
